MACHINE FOR PREPARING FLOCKS FOR FELTING.

' Specification of Letters Patent No. 11,818, dated July. 18, 1854..

To all whom it may concern Be it known that I, LEANDER W BoYN- TON, of South. Coventry, in the county of Tolland and State of Connecticut, have invented a new and useful Improvement in Preparing Flocks for Felting, &c.; and I do hereby declare that the following is a full, clear, and exact description of the construction, character, and operation of the same, reference being had to the accompanying drawings, which make a part of this specification, in which- Figure 1, is a perspective view of the ma chine, when the case which covers the revolving brush, and the stationary brushes, are removed, showing the revolving brush, wire screen, and both of the endless aprons. Fig. 2, is a longitudinal section of the whole machine, cut from top to bottom, showing all the parts in their proper connection with each other.

My improvement consists in preparing the flock, and spreading it on the web of wool, for making felt cloth, &c., by the use of one revolving cylindrical brush, with one or more stationarybrushes fitted on a concave surface, and a wire screen at the bottom, to

preventany flock, not fully prepared, from falling onto the web of wool, but allowing the revolving brush to carry it up again, so that it may be continually worked over till it is fully prepared, when it will pass throlugh the screen and fall onto the web of woo a 'I make the frame, A, A, A, of post and bars, as shown in the drawing, or in any other convenient form, and of any suitable materials. I make two segments of a circle, B, and C, Fig. 2, and fit in concave brushes .in one or both of the segments, as seen at B,

Fig. 2. I connect the lower extremities of these two segments by a wire screen, as shown at D, Figs. 1, and 2, so that none of the flock can fall onto the web of wool, (passing below the screen,) until it is sufficlently separated and prepared to pass through the screen. This screen may be used stationary or with a vibrating motion under the revolving brush, as may be found most convenient or effectual, in any particular case; probably vibrating in the direction of the length of the revolving brush, E, will be found most effectual in cases in general, as tending to sift the prepared flock through the screen, though it may vibrate either way. This screen, D, may also be used under the lower brush where a series of &c.,) where the lower revolving brush is the last brush in the series.

I make, and use, a cylindrical revolving brush, E, Figs. 1, and 2, which is to be re volved, in the direction indicated by the dart, (by any convenient power,) by a crank, F or pulley and band, as found most convenient in each case. This revolving brush, E, receives the flock from the endless apron, G, and carries it over against the stationary brushes, B, and C, which assist in preparing it, and finally brings it down where all that is properly prepared will pass through the screen, D, onto the web of wool, as it is brought from the carding machine, on the endless apron, H. While that which is not sufliciently prepared will be carried up again, by the revolving brush, E, against the stationary brushes on the concave surface of the segment, C, (if any be used,) and again carry it around, as before, so that none can fall upon the web of wool, on the endless apron, H, until it is sufficiently prepared to pass through the screen, D. This revolving brush, E, works upon, and against, the wire screen, D, as shown in the drawings, so that the screen assists in preparing the flock, while the action of the revolving brush assists in forcing the prepared flock through the screen.

I make the endless apron, G, in the common form, and work it by any of the usual methods.

The endless apron, H, belongs to the carding machine which cards the wool, (and the apron is worked by that machine,) and brings the web of wool under the screen, D, of the apparatus for preparing the flock,

and may be at any distance below it, as the flock, when prepared, may fall from the screen through a spout of any required length. I

Having constructed and arranged the apparatus, (as before described,) I spread the flock on the endless apron, G, and put the -machine inmotion, (by any suitable power,) when the endless apron, G, will feed the flock to the revolving brush, E, by which it will be carried over into contact with the stationary brush, B, and after being there acted upon, will carry it down to, and work it against, and with, the screen, D, when so much of the Hook as is fully prepared will pass through the screen and be deposited on the web of wool which is passing, below, on the endless apron, I-I. Should any of the flock fail to be sufficiently prepared to pass through the screen, D, the revolving brush,

E, will carry it up against a stationary brush on the concave surface of the segment, C, (if there be one used,) and around the full circuit again, as before described.

I am aware that brushes have been used for preparing flock, and analogous substances; and that the use of a Wire screen is not new; I therefore do not clalm either of them, as such, as my invention, but,
